Walnut vs Trade Ideas: Which Is Better in 2026?

Prices checked October 2026. A price marked (Oct 2026) was read on the vendor's own pricing page; others are described without a number because we could not verify one.

The AI that knows your portfolio. Ask anything in plain English, research any stock or fund, and get an honest second opinion, on the broker you already use. Read-only by default, you approve every trade, and it never holds your money. Walnut is not an investment adviser.

How it works: You connect the brokerage you already use, read-only by default, so your login stays with your broker and your money never moves. Walnut gives each holding a keep, trim or exit read from its one-year price return against the S&P 500, its momentum and its size, and flags any position above a quarter of the portfolio. You ask follow-up questions in Walnut's own assistant, or inside Claude or ChatGPT through its connector, which only reads. You can turn a thesis into a basket with target weights, and when you decide to act Walnut drafts the trades and places the ones you approve at Public plus eight other brokers including E*Trade, tastytrade and Webull.

In practice, Walnut’s AI reads your real holdings, rates each one against the S&P 500, builds baskets and drafts trades. It is an AI investing app that connects the brokerage you already use, best suited to a keep, trim or exit read on the stocks you already own, and placing the trades you approve. On connecting an account: yes (the brokerage you already use, read-only by default). On execution: places the trades you approve at Public and eight other brokers. Cost: free; Walnut Unlimited $9.99/mo on the web; no fee on assets.

One honest limitation: It has no cost basis or tax lots, so returns are one-year price returns rather than profit and loss, and it is read-only at Schwab, Fidelity and Vanguard.

AI-driven trade signals aimed at active traders. Best for short-term, signal-driven trading.

How it works: Trade Ideas runs an AI engine nicknamed Holly that simulates many strategies overnight and surfaces a fresh set of intraday trade ideas each morning, each with suggested entry, exit, and risk parameters. Real-time scanners flag setups as they form during the session, and some users wire the signals into supported brokers to act quickly.

In practice, Trade Ideas’s AI AI trade signals (Holly). It is an AI stock research and scoring tool, best suited to active, short-term trading. On connecting an account: via supported brokers. On execution: signals + execution. Cost: subscription (premium).

One honest limitation: Priced and built for active traders, not long-term portfolio management.

The honest framing: Trade Ideas is about generating stock ideas, scores, or signals to research, while Walnut is about deciding what to do with the stocks you already own: each one gets a keep, trim or exit read, and Walnut places the trades you approve. Trade Ideas produces research and signals you then act on somewhere else, whereas Walnut connects your real account so the AI works on your actual holdings.

Every tool gives something up for what it does well. Here is the honest give-and-take on each, so you can weigh the specific strengths against the limitations that come with them rather than judging on the headline category alone.

For AI investing tools, the distinction that matters most is whether the tool works from your actual, connected positions or reasons from something else: a separate account it manages for you, or the tickers and numbers you feed it. It decides how personal the answers can be, and where your money physically lives.

• Walnut: reads your real connected holdings. Walnut connects your real brokerage (Yes (the brokerage you already use, read-only by default)) and works from your actual positions, so its answers reflect what you genuinely own rather than a generic model.
• Trade Ideas: connects specific supported accounts. Trade Ideas connects a defined set of accounts (Via supported brokers), so whether it can see your holdings depends on whether your money is at one of them.

This is where they diverge most. One works from your real, connected account while the other does not, so if you want an assistant grounded in the exact positions you already hold, that gap is the thing to weigh first. This holdings-aware angle is the one Walnut is built around: it connects the brokerage you already use and reasons from your live positions, read-only by default, with any trades left for you to approve.

Each one wins a different job, so the answer is committed per job rather than overall.

• Choose Walnut if you want a keep, trim or exit read on the stocks you already own, and placing the trades you approve. Its AI reads your real holdings, rates each one against the S&P 500, builds baskets and drafts trades, and it costs free; Walnut Unlimited $9.99/mo on the web; no fee on assets. It is built for investors who already own stocks at a broker and want an AI investing app to tell them which to keep, trim or exit, without moving their money. Keep in mind: it has no cost basis or tax lots, so returns are one-year price returns rather than profit and loss, and it is read-only at Schwab, Fidelity and Vanguard.
• Choose Trade Ideas if you want active, short-term trading. Its AI AI trade signals (Holly), and it costs subscription (premium). It is built for active short-term traders who want AI-generated intraday setups with entry and exit levels. Keep in mind: priced and built for active traders, not long-term portfolio management.

Because they sit in different categories, this is not strictly either-or: some investors use one for a keep, trim or exit read on the stocks you already own, and placing the trades you approve and the other for active, short-term trading, and watch for overlapping costs.

Cost is easy to misread when two tools charge in different shapes, so compare the model, not just the number. Walnut: free; Walnut Unlimited $9.99/mo on the web; no fee on assets. Trade Ideas: subscription (premium). A percentage-of-assets fee scales with your balance, a flat subscription does not, and a “free” tier usually earns elsewhere (on cash, order flow, or premium upgrades), so the cheapest headline is not always the cheapest outcome for your situation.
